Background and Objectives: Today, overweight and obesity are among the significant challenges in the world. They can have adverse effects on quality of life. Quality of life is determined by social and physical environment. The present study investigated the construct validity of the Persian version of the Impact of Weight on Quality of Life (IWQOL-lite) questionnaire using multilevel confirmatory factor analysis.
Methods: The present study was conducted on 310 people over 18 years old living in Yazd city. The data were analyzed using m-plus6.2 software.
Results: The mean age of the participants in this study was 33.97± 4.70 years. Sixty percent (N=183) of subjects were male. The indices of the one-level model were more appropriate than those of the two-level model, and the one-level confirmatory factor analysis model had a good fitting to the data (CLI: 0.98, TLI: 0.98, RMSEA: 0.038).
Conclusion: The results of this study indicated the need for more effectiveness of urban areas on quality of life. The one-level confirmatory factor analysis model confirmed the construct validity of the IWQOL-lite questionnaire. This questionnaire can be used in the Iranian population.
